the second week of calc is over and i feel like i know a good bit even though its eof my hardest classes.it's getting better. I am understanding everything a lot better.

last year i slacked during the log chaper and i didnt know it because i played block dude everyday. I get everything from last year with the normal logs too. john taught me all the logs from last year. Log4=x which equals x=2 thats prettty easyyy. i understand the natural log properties from this past week when you plug everthing into the formula and simplify. Its pretty easy most times. we have ln(x^5). You plug into the ln formula, 1/u * u', and you get 1/x^5 * 5x. When you multiply you get 5x/x^5 which simplifies to 5/x (you cancel the x's). I understand that you may have to deal with multiple formulas in one problem. An example would be ln(x/(x^5 + 1)). In this problem you can see that you have to deal with natural log and quotient rule.

Something I don't understand is the difference from u^n and a^u. and i dont understand the arc trig functions with all the algebra. all the algebra in these problems mess me up and i end up messing it up. i hear sarah is pretty good at those btw hahahaha

everyone is at my house at the moment studying the test we have on wednesday. is that a test or a quiz because we are not too sure. can someone answer that question as well?
